Molecular Geometry and AXE Notation

The video tutorial explores the molecular geometry, bond angles, and electron geometry of ICl2-. It begins with constructing a valid Lewis structure and using AXE notation to determine the geometry. The tutorial visualizes the structure in 3D, showing the linear molecular geometry and explaining the bond angles. It also covers the electron geometry, which is trigonal bipyramidal, and concludes with a recap of the key points.
